Cryptogenic strokes are now thought to comprise about 25% of all ischemic strokes. These unable find a precise mechanism ischemia after standard workup, including transthoracic echocardiography, 12-lead electrocardiogram, inpatient cardiac telemetry monitoring, 24-hour Holter magnetic resonance imaging, and various vascular imaging neck brain arteries. Additional investigation identifies likely in more than half these patients, such as cancer, aortic complicated lesion, coagulation disorders, etc. Most cryptogenic cerebral embolism, arising from proximal arterial sources, heart, and/or venous sources. Patent foramen ovale (PFO) is found up young adults with stroke, then percutaneous devices for closure PFO should be used them careful inspection.
